What l claim as new is:

L in a switch, the combination of it fixed. nontnct, a n'iomble contact, :1 member on which Said movable contact movobly zm-aznteil, ans? actuating means for said nimnbc comprising means for causing the ililiil ilOFlElg .i'novement of Faiil movable contact to be approxiniatet-ly parallel to the on gaging surface of said fixed contact, and said actuating means colipernting with said movable mounting to increase the prcssurc with \ihich said movable contact bears on said fixed contact.

In a switch, the cmnhination of I'8liltively movable contacts, a nvmhcr carrying onev of said contacts, a. linh connecting said one contact and said member and hiaiml to draw said contact tmwnl mu monibvn :1 support. and inccmo assirciutcil with said support and 5:1 iii member for actuating said member to move said. contacts into ciosml no sition mid to produce relative separation be tiwrmi hiiid one contact and saiil member.

in a switcln the combination of a min port. r alc .n'ciy movable contacts a member carrying one of said contacts and connected thereto by means permitting relative separation and approach of said mcmhor and the contact carried thereby, and means operative during the closing mm'cnwnt of said switch to cause movement of said member and its contact together and subsequently to act in coiiperation with said member and said contZlCtS to cause relative movement between g'ziging surface of said fixed contact, a menr her flexibly connected to said movabiecon- 139 tact, a support, a link connecting said niemher and SHlCl'SUPpOIt, and means'for actuating said member, said link cooperating ber on which said movable contact is movably mounted, a support, said member being movablymounted on said support, and an actuator for pressing said movable contact .into engagement with the stationary con.-

tact, the movable mounting of said movable contact and said member cooperating with said actuator to cause said movable contact to first moveover said stationary contact with a wiping action and then causingrelative movement between said movable con tact and said member.

7. In a switch, the combination of a stationary contact, a movable contact, a member on which said mo'v ible bontact is mov ably mounted, and means for actuating said member to presssaid movable contact into engagement with the stationary contact, said movable contact first moving over said stationary contact with a Wiping action and then said actuating means cooperating with said movable mounting to cause a relative movement between said movable com ict and said member.

8. In a switch, the combination of a stationary contact, a movable contact, a member associated with said movable contact, a link connecting said movable contact and said member to permit said member to move to and from said movable contact, and means for actuating said In nber'to press said movable contact into engagement with said stationary contact, said movable contact first moving over said stationary contact with a wiping action and then said actuating means cooperating with said link to produce relative separation between said movable contact and said member.

9. In a. switch, the combination of a fixed contact, a cooperative movable contact, and

actuating means for said movable contactao effective during the switch-closing operation to cause movement 0 said movable contact in a direction approximately parallel to the engaging surface of said fixed contact when said contacts-are first brought into engagement and to subsequentlyincrease the res-- sure with which, said movable contact on said fixed contact.

10. In a switch, a support, a. fixed'con tact, a member having a contact portion w adapted to engage said fixed contact, links connected at one end to, said memberanil at the other end to said support, said links being connected to said member and said support at different points thereon, and means for imparting motion to one of said links to actuate said member, a portion of the latter part of the closing'movement oi the points of said links connected to said member being approximately parallelv to the engaging surface of said fixed, contact,

ears

whereby a wiping action between said fixed I and movable contacts is secured.

11. In a switch, the combination of, a fixed contact, a cooperative movable contact, a.

member on which said movable contact is. movably mounted, and actuating means for said member operative during switch-closing movement to causemovement of said contact in a direction approximately par allel to the engaging surface of said fixed contact after said contacts are first brought the switch-closing operation to increase the pressure with which said movable contact bears on. said fixed contact.
